Re: Valve seals
I checked a block in a C10m for my daughters boyfriend. He was told it was a 327 when he purchased the truck.
Well two out of three numbers taint bad. It was a 307.
The large CC chambers have dropped the compression substantially. It's easy to spend your money but the replacement heads could really wake up your motor with both a increase in breathing and compression.
Or just put the springs and seals in and enjoy the ride. One has to remember "it ran before!"
cheers.
